Abstract

The invention relates to an abrasion-resisting and corrosion-resisting composite impeller, and belongs to the field of fluid machinery. The composite impeller comprises a metal wheel hub and a ceramicblade; the center of the metal wheel hub is provided with a connecting ring, and the outer wall of the connecting ring is provided with connecting rods in a radially outward extending mode; the ceramic blade is of an impeller blade structure machined through ceramic materials, and a hub positioning groove which is matched with the front end of the metal hub in appearance is reserved in the centerof the rear end of the ceramic blade; and the metal hub is inserted into the hub positioning groove in the rear end of the ceramic blade, and the metal hub and the hub positioning groove of the ceramic blade are glued and fixed through resin glue. According to the abrasion-resisting and corrosion-resisting composite impeller, the structure is simple, mounting is convenient, the problem of fast corrosion of the impeller under high abrasion and high corrosion working conditions is solved, and the cooperating problem of the ceramic impeller and a shaft is also solved.

Description

technical field [0001] The invention relates to a wear-resistant and corrosion-resistant composite material impeller, which belongs to the field of fluid machinery. Background technique [0002] In many coal mines and many working conditions in the metallurgical industry, there are strong abrasiveness and corrosion. The solid content of the slurry in this working condition is very high, and the particles are relatively hard. In this working condition, there is strong abrasiveness and corrosion, and the impeller is the part that is most eroded and corroded by the slurry. The traditional metal impeller has longer wear resistance and corrosion resistance. Therefore, the wear resistance of the impeller should be enhanced. Corrosion and corrosion resistance are very important. The wear resistance and corrosion resistance of ceramic materials are very superior. However, the ceramic material is highly brittle, and the impeller of the ceramic material needs to cooperate with the m...
